My invention" relates to means designed for assisting or training the"golf player tomaker a more perfect swing in order" to project tiie golfballfo'nthe desired the of flight.

Theaot of addressing a golf bail involves body movements designed toaccomplish a posture or stance calculated to insure" a satisfactory golfstrolie'bothasto the direction and distance the ball is projected) Theaddress of" the ball is ordinarily' identified over'a period ofyears-that the position and angle" of the players head during: theaddress and stroke have an" important influenoe'on the satisfactorydispatch of the golf ball for the purpose'referredto: In fact, ithasbeen" found tiiat; withthe-headproperlv positioned; the body willoften naturally assume the" necessary postuie for accomplishing a goodstroke:

Wiifle'it mayioe assumed that the person betretined couldfollowinstructions with a- View to securingand maintaining the correcthead positionduring-the address and golf stroke, it is often diffi'cultfor one to remember to assume such head position every time-he tries topractice or play" golf. It is thereforethe principaP object ofmyinventionto provide an adjustable appara tus whioiiinduces the pro erhead" andconsequent" bodypostureth'rough the medium ofa tail sightingdevice.

Another object is to provide a device ozf" the aooveoharacter which"employs an obj ec'tive for sighting thegolf lo'all with both eyesandindi oa'tes tide head position or change therein to the player by atprescribed condition in thesighting zone; such-deviceoperatingbymeans-of an aperttime having a pre'soribed" outline rather"than any legend or marking directly in the'patl i of vision tbwardthe'bail and" aptto interfere wit-n such vision:

Anotti'e'r' ooject is* to provide an apparatus which is in convenientpositionand can be emitted to" suit" the height and osition of any so oninorder to facilitate the" sighting of the go ail andthe-execution ofthe stroke" to dis patch th'e bail ontii'e" desired line of flight;

A further object is t'o provide an apparatus of the aliov e charactermay be handled: with convenience or rolded to ooeupy a oom aot spacewhen not inruse.

A1 stiiii iurther obieoti is to oonstruotl the novel apparatus alonglines: of? mechanical. efficiency and for economy of manufacture.

Referring specifically; to: the drawings, one form oi: the: apparatus:isziinten'ded for: suspension from a ceiling or other overhead supportand involves basically a canopy it which is attachable by bolts or othersuitable means M to the overhead support 42. A telescopically adjustablerod 43 depends from a conventional adjustable ball joint 43a made withthe canopy id, and receives a socket M at the bottom to form a balljoint 45 with a bracket 46, a spring 41 imparting pressure to the jointin order to keep it in snug engagement. The bracket 36 is threaded, asindicated at 46a, to receive a web 38 projecting from and forming partof an attaching plate 49, nuts as on both sides of the web beingthreaded on the bracket portion 46a to render the web adjustable alongthe bracket.

The attaching plate 45 is designed to support a light plate 55 of metal,wood or plastic material by means of screws 56, such plate beingperforated to form a sighting unit. The plate is recessed from the frontas indicated at 57 to seat a panel 57a perforated in registration withthe sighting unit, the latter being of oblong form with the majordimension horizontal. The plate and panel are made with opposedprojections 58 extended from the sides toward the middle; and theseprojections carry slides 59 which may be gathered or separated asindicated by dotted lines in Figs. 2 and i. The extent of slideadjustment is calibrated by having a measuring scale 6%) made on eachprojection 58 and a slot Bl made in one face thereof to expose thecorresponding slide 59, the latter having an origin mark 62, as shown inFig. 4.

. Fig. 1 shows the plate 55 adjusted to an angle designed to facilitatethe sighting of a golf ball 63 mounted on a tee 64. The ball is viewedthrough the opening 85 in the panel 51a and plate 55, as indicated inFig. 2; and its position ordinarily appears visually midway between theslides 5S3, though not necessarily midway between the ends of theopening 65. However, in viewing the ball with both eyes as in Fig. 2, Ihave found that the optical effect is a gathering of the side elementsin the opening 35, so that it is actually easier to fix the position ofthe ball as seen through the aperture of the sighting unit. It follows,where the panel is adjusted properly by the teacher with reference tothe sighting of the ball, that the novice golfer will have to positionhis head accordingly in order to properly sight the ball for the coursehe intends it to take, so that the position of his head follows a pre--scribed arrangement and is the same every time he approaches theapparatus, assuming he places the ball in the same relative position.Obviously, practice with the apparatus will teach the golfer theprescribed head position, so that he may assume and maintain suchposition naturally during the stroke when he goes out on the golfcourse.

It will be apparent that the form of apparatus just described is limitedto indoors or a practice court, and I have therefore devised the moreelaborate second form which may also be used out in the open. Referenceto Fig. 6 shows that such form of the apparatus is erected on a verticalstandard it having a base 15. Fig. 14 shows the base portable forplacement on a floor or other surface, while Fig. 13 shows how the baseH may be eliminated and a concrete foundation Ha provided as a permanentbase for the apparatus. Also, the standard it may be extended upwardlyor rearwardly as indicated by dotted lines in the upper right-handportion of Fig. 14 to secure the support of the apparatus from a ceilingor wall. A sleeve '12 is mounted and adjustable along the standard 10,the lower end of the sleeve carrying a transverse flanged plate 13. Acompanion plate M is carried slidably by the standard 10; and the levelof the plate '53 is adjustable to several heights by making transversebores 16 in the standard at desirable vertically spaced points andapplying a key Tl through the plate '14 and the chosen bore. The sleeve12 is also rotatable on the standard l6; and a lining 18 of brakematerial is interposed between the plates 13 and M, in order that thesleeve 72 may remain stationary through friction at any point to whichit may be turned. A spring 19 is coiled around the bottom portion of thestandard it to rest on the base H and form a shock absorber in casesupport of the apparatus fails when the key '11 is removed.

It is intended that the standard 70 and its sleeve 12 form the basicsupport for a sighting unit similar to the plate 55 and panel 51apreviously described, and means are extended from the sleeve l2facilitating the positioning of the sighting unit at various heights andangles.

In carrying out the means just mentioned, the sleeve 12 is extended withupper and lower channel members 88 and 8!, the backs of the channelmembers being welded to the sleeve. The sides of the channel member 853are employed for pivoting upper and lower pairs of square parallel tubes82 and 83 at 84 and 85, respectively. These tubes are inclined towardand beyond the rear of the sleeve 72 and terminate along the inner sidesof a channel member 86 whose back 81 is in a rearmost position. The endportions of the tubes 82 and 83 applicable to the channel member 86 arepivotally secured thereto as indicated at 88 and 89. The channel member86 also receives a pair of links 99, these being secured pivotally tothe channel member 86 as indicated at SI and inclined in forwarddirection, terminating alongside the upper portion of the channel member8|. Here the links 90 overlie a pair of bows 92 applied to the sides ofthe channel member 8|; and special bolts Ill pass freely through thelinks 90, through the bow sides 92, through the brake linings I53 andinto vertical slots 95 made in the channel member sides 8|.

The forward end portions of the pairs of tubes 82 and 83 are appliedexternally to the diagonally opposite corners of a pair of verticalplates I00 as indicated at NH and I02, such plates being rigidly joinedby a cross-web 103. Two pairs of parallel tubes Hi4 and H35 extend invertically spaced relation along the inner sides of the plates it, beingpivotally attached to the remaining corners thereof as indicated at l0!and I08.

The tubes H14 and I05 are inclined oppositely from the tubes 82 and 33;and the rear ends of the pairs of tubes 19 and W5 terminate along theinner sides of a channel member W9, being pivotaly attached to suchsides at iii] and Ill, respectively. The forward ends of the pairs oftubes i641 and [05 terminate along the inner sides of a channel memberH2, being pivotally attached thereto as indicated at H3 and H4,respectively. While the back of the channel member N99 is located at therear, that of the channel member H2 is located in front. A pair of linksH5 extend between the pairs of tubes 83 and W5, as seen in Fig. 6.'Thus, the rear end portions of the links H5 are pivoted to the tubes 83at Ht, while pivot units ill pass through longitudinal slots H8 made inthe tubes 1B5.

The structure so far described in connection with the supporting sleeve12 is designed not only m: rotary horizontal and vertical adjustment,but also for folding into compact space. Thus, while .Fig. 6 shows thestructure in an extended position for use, Figs. 13 and 14 show itfolded into compact vertical form. This is done by backing the series oftubes in a manner to swing on their pivots and gather toward each other.It is also intended that the structure remain in any position ofextension by being self -balanced; and the balancing means are containedin the structure. Thus, to avoid the tendency of the structure tooverloalance forward direction, the channel member 85 receives acounterweight I21 externally in order to provide clearance within themember in respect to the standard sleeve 12., permitting the tubes 82and 83 to froldparallel vertically with the tubes HM and ms when theapparatus is gathered as stated. The channel member 1:09 is equippedcompactly with an inter nal weight I241. The condition applying to thepresent apparatus :also applies to the standard 10 which depends fromthe ceiling as indicated by the dotted lines in Fig. 14.

It is essential that the adjustment of the links H5 relative to the pairof tubes I05 contain a sliding friction factor in order to maintain anydesired setting between the links and tubes without fastening oradjusting expedient-s1; and Figs. 8 to 11 show the friction meansemployed. Thus, the pivot I ll represents the end flanges or heads of apair of alined tubular bolts I25 (see Fig. 10) previous y indicated asspecial bolts, these passing through the links I I5, washers .lfill,bows sides 'I5I, brake linings I53 and the sides of the tubes i105. Thebolts I25 continue toward each other and terminate in opposed relation,such as indicated in Fig. 8. Between the tubes 1I05, the bolts I2: arecontained in a hexagonal tubular casing I21 AllOd I2?! is contained inthe bolts :I 225 to maintain them in alinement; and a sleeve I 28 isriveted on the rod as indicated at I29 and serves as an-end stop for therod in relation to the bolts I25. The latter are threaded externally inreverse directions :on their innermost portions, as indicated at [3.0,into hexagon nuts I3I mounted in the casing 426 in a manner to slide butnot turn relation to the same, as clearly shown in Fig. 9.; and thebolts are slightly flanged endw-ise as shown at I32 to primarily lockthe nuts IBI from running off the bolts.

'lhe bolts I25 carry freely plates I31 located endwise of the casingI26, such plates having end flanges I39 and being separated from thecasing by washers 3B which overlap the tubes I05 and lock theplates'fromrotating relative to the tubes. One of the plates I37!isshown in Fig. ll, and it is seen that it has keys I40 entering itscentral opening M]. Fig. 10 shows that the inner portions of the tubularbolts 125 are formed with diametrically opposite slots M2. Thus, thekeys M enter the slots I42 and prevent the bolts II-'5 from rotating.Compression springs I 36 are mounted on the bolts 1 25 between the nutsI31 and the washers I38.

It is now apparent that the casing 126 maybe cmployed as a manualcontrol tending to gather the ibOllZS I125 through turning the nuts I 31compress springs I36. This action is intended to impart an adjustablepressure between the links H and the tubes r0 5. this respect, itisnoted from Fig. 8 that the spring compression acts on the heads IIFIof the bolts I25 which bear on the links I15, and through thewashers l5ll, bows Iil and brake lining M3 induces the pressure men- It is nowapparent thatthe inward pull on each bolt I125 will induce a frictionalengage, ment between the bows I5] and tubes I05 by way of the brakeelements I53, rendered yielldable to the compression springs I35 andcontrolling the freedom .of movement between the H5 and the tubes 105,whereby to maintain the setting of these parts until the user desires achange of position thereof.

The assembly of the tubular bolts 1.25 in rela tion to the channelmember .85 and links 90 will be identical with that of the one shownFig. .8, except that the bows 92 will only engage the sides of thechannel member :81 from the outer side;

assemblies of the pivoting elements .84, .35,

'88, 8'9, 91, W1, M2, H31, 103, 1.1.1], I, M3 and I M are generallyidentical and illustrated Thus, the t1ibe;8.3 and link I.I5 may serve asan example wherein the tube is perforated 'to seat a bushing 4515 havinga flange I56 serving as a bearing :for the bolt and its head 135.. TheIbOlt passes through a washer l 5] on the opposite .side and is finallyreduced to form ascrew I58 threaded into the link H5. The washer servesas a spacer to keep the parts in proper relation; and the assemblyfacilitates the free pivoting of the tube and link-or plate or flange,as the case may bewhile keeping the same firmly secured against theshoulder of the bolt.

The channel member I I2 forms an adjustable support for the sightingmechanism. Thus, Figs. Z7 and 15 show that a plate I60 depends from thechannel member M2 to terminate with a realwarcl'ly deflected portion mi.The upright portion oi the plate receives a bolt Hi2 secured by nutsl63..on both sides of the plate, the front end of the bolt having a knobIfi l which is employed to move the channel member H2 in any desireddirection when changes in the adjustmentor folding of the sighting unitare desired.

The pendent plate Idll receives an inclined bracket I68 on the rearside, the bracket being hinged to the plate at I69. The bracket I68 isdesigned to support a plate I'IE! similar to the plate 55 tor angularadjustment. Thus, Figs. 7 and 15 show that the upper portion of theplate l Ifl receives weights I'I'I on both sides, such weights beingsecured to the plates by rivets I72.

The plate ill! is formed with a large circular opening H3 in its upperportion which forms a clearance for a ball joint assembly carried by thebracket I168. Thus, Fig. 19 shows that the bracket is perforated andtapped at Il5 to receive the one-piece receptacle H8 and socket I'TI ofthe ball joint, the lower end of the socket hav'inga circular opening:I'lfi. fhe ball is shown at I80, and a dome-shaped retainer I'8I ismounted over the same, the upper portion of the retainer also having acircular opening I152. The retainer is marginally flanged at I83 toreceive the pressure of a coil spring m4 located in the receptacle Ilfi;andthe latter is tapped as indicated at I85 for the application of apressure ring I86 to control the flexibility of the ball joint. Thepressure ring has an enlarged knurled knob 186a for manual control. Theplate II'Il is thus adjustable angularly by means of the ball joint tolocate the sighting unit at the desired angle.

Figs. '7 and 17 show the plate I10 in the verti cal position, whichcorresponds to the folded position of the apparatus. However, when theapparatus is to be used, the bracket I 68 is swung in forward directionto the position indicated by dotted lines in Fig. "7. Here a screw I I8?013- erated :by a knob 183 passes through the portion 7 'Ifil of theplate I60 to thread into a tapped aperture I89 made in the bracket I68,whereby to retain the bracket to the plate I50 and bring the plate I'iIidown to a position where it may be maneuvered for sighting accuracy. Thescrew I8'I is retained to the plate portion I6I by a plate 190 which isbifurcated at [9i to straddle the shank of the screw and bear on acollar enlargement I92 of the screw. The plate I90 is held in spacedrelation to the portion I6I by three screws I93 which receive spacingwashers I94 between the plate Hit and the portion IfiI.

The plate H6) is equipped with a lamp housing I95 having a rearwardlyfacing spotlight Hit. The current supply cord 593 for this bulb extendsfrom the channel member II2 to loose form as indicated at N39 to enter atube 2% in the center of the plate I'll? and pass through the ball jointas indicated in Fig. 19. The tube is split near each end as indicated at2B! and the ends flattened and riveted to the plate I10 as shown at 262.The cord returns into forwardly directed position through a tubularbracket 203 connecting with the lamp housing I95. The spotlight isdesigned to emphasize the position of the ball 53; and the lower part ofthe plate I10 is deflected rearwardly as shown at 294 to facilitate thesighting on the illuminated area of the ball, as seen in Fig. 18.However, the part 204 may be separate and hinged or pivoted to the plate178 in order to make the angle of the sighting aperture variable inrelation to the plate IHl.

Where the first form of the apparatus illustrated in Figs. 1 to 3 isemployed, the following method of use is properly advisable: The playerfirst grasps the telescopically adjustable rod, which is parallel to theceiling as held by the clip 39 when not in use, and pulls it down to amore or less vertical position. He then adjusts the length and angle ofrod 43 and the angle of plate 55 so that this plate is roughly at rightangles to his sight on the golf ball 63, all as shown in Fig. l. Theball will appear to the player through the opening 65 as shown in Fig.2. The player will have an unobstructed vision of the ball with botheyes. It will be noted that the slides 5e will appear to the playersvision with both eyes as shown in the dotted lines. The effect of visionwith both eyes is a considerably gathered position of both slides asshown by dotted lines in Figs. 2 and 4. The actual gathering of theslides can be adjusted and recorded by use of the calibrations on panel57a. The width of the slides 59 could be the same as the apparent visualdiameter of the ball as seen through the opening 65 in Fig. 2. This isintended as a considerable advantage in restricting the players headmovement because with the slightest raising or lowering of the headduring a stroke, the ball appears decentered vertically between slides,and with any sidewise movement of the head the ball appears decenteredlaterally between the slide ends.

Though the actual gathering of the slides is adjustable as justmentioned, the most satisfactory setting of the slides will be when theoptical effect of the slides for the player is about as shown in dottedlines in Fig. 2, that is, when the ball appears equidistant from theends of the slides and the top and bottom of the opening. The object ofsuch adjustment of the rod 43, panel 55 and slides 59 is to have thegolf ball appear in the vision of both eyes of the player through theopening 65 in such a manner that when the player executes a golf strokewhile keeping his eyes on the ball any movement of his head will givethe optical effect of the ball itself moving out of the center of theaperture made by the ends of slides 59 and the top and bottom of opening65. Thus, by practice, the player will endeavor to maintain his opticalvision of the ball in the center of the aperture above described whileexecuting his golfing stroke. Such practice would train the player'shead to remain as stationary as possible, which habit would bebeneficial when the player is out on the golf course in actual play andaway from the apparatus. The use of this apparatus is particularlyvaluable when golf instructions are being given by a professional orteacher .to a pupil. After the teacher places the golf ball 63 in asuitable position, he makes a preliminary adjustment of the position ofthe aperture in opening 65 of the plate 55 by adjustment of the lengthand angle of rod t3, adjustment of the angle of plate 55, and slides 59.

After making the above preliminary adjustment, the teacher has theplayer take his stance and endeavor to sight the ball through theaperture. The teacher will readily note what adjustments in theapparatus will need to be made in order that the pupil will stand at thecorrect distance from the ball and so that the pupils legs, arms, bodyand head will assume the proper relationship for a correct address inrelation to the position of the ball and the direction in which it is tobe dispatched.

The pupil and teacher may note the position of the golf ball andadjustment of the apparatus so that the pupil may more easily assume thecorrect golfing pose or stance for future practice. The great benefit topupil and teacher because of the apparatus is that the pupil, byobserving the ball through the aperture, can himself work to keep hishead still, leaving the instructor free to concentrate his efforts onthe various movements connected with the proper execution of a golfingstroke.

Since many movements in golf, as well as balance, are apt to be upsetwhen the player moves his head, the simple procedure of the player beingable to have a mechanical guide to reduce the movement of his head asfar as possible will in turn greatly facilitate the teachers orprofessionals task in grooming the players movements and balance in acorrect swing, thus tending to rapid progress of the player in improvinghis golf game.

Even the most experienced player or champion, who knows just where hishead should be positioned, will find the apparatus an effective helptoward reducing his head movement and improving the quality and accuracyof his play.

Figs. 6 through 19 depict a second form of the apparatus with a moreelaborate mounting and a slightly different form of panel and openingthan above described in the first form of the apparatus. Before usingthe second form thereof, it should be noted that the standard '10 shouldbe mounted vertically, whether depending from a ceiling or wall or setinto a portable base, as shown in Fig. 14, or being embedded in concretein the ground, as in Fig. 13. When the player is ready to use thissecond form of the apparatus, he would normally find it collapsed as inFigs. 13 and 14. The player would first grasp the knob I64 and, bypulling it toward him, would open and extend the apparatus as shown inFigs. 6 and 7. (The apparatus us usually rotated, extended,

gathered, raised or lowered by the player grasping and exerting force onthe knob I64.) He will then, while holding the knob in his left hand,pull the plate I76 toward him until he can engage the screw 18'! intothe inclined bracket I68 by turning the knob I88. The plate Illl is thenadjusted to the desired angle by continuing to hold the knob I64 withthe left hand and grasping and adjusting the plate I'Hl with the right.When a satisfactory adjustment of the plate H is reached, the knurledknob 186a on pressure ring I86 might be tightened, if necessary, to havethe ball joint in Figs. 7 and 19 hold the plate H0 a little more firmlyin the adjusted position.

The apparatus should remain in the selected position until moved again,since it is balanced by counter-weights I29 and I21, as shown in Fig. 6.The plate 116 also has a balancing counterweight IH.

A further help to aid the plate I'll) of the apparatus to maintain somepreselected extended or folded position may be found in the adjustablesliding friction factors operating on the pair of tubes H at H? and thechannel member Bl,

also at H7, and the ball joint as shown in Fig.

brake lining 16. The flanged plate brake lining 21 for friction at 13, Mand 1'8 will be made of sufficient diameter to prevent the apparatusfrom rotating when not desired because of some slight force, such as thewind. All the aforementioned four sliding friction factors can havetheir tension f I so preadjusted that they will not need to be changedfor considerable periods of ordinary use.

It will be noted that the plate ill] has a lamp housing 695 andspotlight 196, the beam of which the player can aim in the direction ofthe golf ball at night to make the ball stand out sharply in the playersvision. The lower end of the plate at 204 is bent slightly so that arightangled light of the beam to the upper part of the plate I10 and theplayers right-angle vision at 204 will more nearly converge on the ball(see Fi 18).

The advantages the player will enjoy in using the more elaborate secondform of the apparatus besides having a light directed on the ball fornight practice-are that this form has many independent adjustmentsallowing a fine setting and a relatively greater stability inmaintaining such finely set position. Also, for players of dif ferentheights the apparatus may be lowered or raised on its standard 19 byinserting the key '11 in various transverse bores 16 (see Fig. 6). Atthe end of a days play the sleeve 12 hearing the collapsed apparatus maybe raised off the standard l0 merely by unscrewing the top cap andremoving the key TI. Various forms of the panel 51a and the opening 65are shown in Figs. through 26. The optical illusion or visual effectwhen the ball is viewed through the aperture with both eyes is shown inFigs. 20a through 2612. It is understood that other forms of aperturesmay be employed for viewing the golf ball, such as conical, circular,rectangular, etc.
